BITMAIN Antminer S19 86TH/S Bitcoin ASIC Miner(34J/T, 220V, 2967W, SHA256 Algorithm), High Hashrate/High Efficiency Air-Cooling Home Mining Machine for BTC/BCH/BSV w/o Power Supply

Seems to be working like advertised. I'm using to it to heat my house when I'm not there to build a fire. Otherwise this would have to be in the garage or another room because it is loud like a server.

Excelente

Good Buy! It is advertised as 96 Th/s but I actually get 105 Th/s average! Fast shipping, and even though you pay for shipping it’s still cheaper than other options.

Make sure you do plenty of research before ordering this machine. Power noise, and heat.

Functioned as described. Support was wonderful. They helped me get everything set up.

I absolutely love these units. Every S 19 unit I run into that is a proper working condition works fantastically not as good as an S 21 but fantastic.

Unboxed antminer and it was dirt but worked i recommend cleaning them because I would of have bought more if they where clean

Arrived just as promised.
